for sure I would be interested. only problem I see with a DIY project is its likely to include an NDA. I posted about this a while ago, thats one hell of a crazy looking eval board! blew my mind when I saw it last time I looked

wasnt a thread, was a post, so its not surprising you didnt find it. no I just suggested it as a usb controller for one of the input boards for the ackodac sabredac. jkeny ended up putting together a modified MTECH HIFACE for it, but I would much prefer a proper input board with the possibility of multichannel.

what I meant was, only you or whoever had the NDA would be able to build up the board, meaning only fully populated boards could be bought from you. interesting, but not ideal, because unless you offered something the mtech doesnt ie multichannel, or it was considerably cheaper than buying a hiface and modding it yourself, there really isnt anything gained and I would rather just stick to something I have some input into. i'll still be watching though

A tiny bit of surgery seems to solve this. And the custom drivers are essential if you want async. All in all, unless Gordon suddenly gets interested in selling TAS1020b chips and drivers to diyers, the hiface appears to be the only route to good USB sound.
